(1)
From this it is understood that it is not necessary to have a separate garment for marital relations.
(2)
Due to the state of major ritual impurity (janabah), the garment that is worn on the body during sexual intercourse does not become impure. However, if something gets onto the clothes, then wash that part of the garment and perform the prayer; otherwise, there is no need to wash it.

295. Commentary: By impurity is meant the presence of semen, blood, or similar substances. If such impurity is present, then washing the affected area is sufficient; otherwise, it is permissible to pray in that garment as it is, because in the absence of impurity, it remains pure.
